UNITED STATES PATENT OFFIGE;

IMPROVEMENT IN SHOE PEGS OR NAILS.

Specification forming part of Letters Patent N 0. 169,839, datedNovember 9, 1875; application filed October 4, 1875.

To all whom it may concern:

Be it known that I, TREAT T. PROSSER, of Chicago, in the county of Cookand State of 1 Illinois, have invented a new and useful Improvement inShoe Pegs or Nails, of which the following is a specification:

This invention relates to that class of shoepegs which are provided witha notch near the point to facilitate the clinching of the point, drivingthe peg through the leather up against a metallic anvil.

My improvement consists of a chisel-pointed peg or nail, the chisel-edgeof which is slightly oblique, and in which the notch is arrangedtransversely to the chisel-edge at the longest side.

Theadvantages of this peculiar construction may be briefly stated asfollows: Were the chisel-edge square with the nail or peg it wouldnecessitate-the use of a deep notch, extending beyond the axis of thenail-or peg, to cause the desired clinching, for if the notch were moreshallow the point of the peg on striking the anvil would merely upset,not clinch; but by making the chisel-edge a little oblique, with thelongest point directly under the notch, the clinching can be effectedwith certainty and little force by the use of a comparativelyshallownotch, which will not materially weaken the point, so that it will notbend before it strikes the anvil, as it would be liable to do did thenotch extend more than half-way through it. The point will bend towardthe notch, of course, in clinching. It is desirable that the end orpoint'of the peg should bury itself in the insole in clinching. This isgreatly facilitated by arranging the notch transversely to thechisel-edge, because in this way the point, in clinching, presents oneof its side edges to the insole, which such edge will readily enter.

In the annexed drawings I have shown headless pegs, one form illustratedbeing smooth and the other form full of indentations on the surface. Thechisel-edge of the point is slightly oblique or beveled, so as to makethe nail longest at the side of the corner a of the chiseledge. Thenotch 12 is directly over this corner a, and is arranged transversely tothe chiseledge. These pegs are usually produced by the machine, whichdrives them, as soon as made, into the'v boot or shoe to be pegged, bycutting them successively from a coil or length of wire.

In the particular pegging-machine employed by me the notching-tool has aslight lateral motion to give the required obliquity to the chisel-edgein the act of notching the wire. This effect may, however, be producedin other ways.

What I claim as my invention, and desire to secure by Letters Patent,is-

A peg or nail having a slightlyoblique chisel-edge and a notch near thepoint, transverse to the chisel-edge and acrossthe longest side,substantially as and for the purpose specified.

In testimony whereof I have signed my name to the foregoingspecification in the presence of two subscribing witnesses.
